I'd say "just play the bloody music" ... I go to gigs to listen to a performance not to watch it. If your strange facial and bodily tics are what comes naturally, that's fine. If they're affected, that's sad. The same goes for singers and players who get near a stage and suddenly believe they are stand up comics or all round light entertainers. In most cases they're not - and I can't remember ever going to a gig for the 'witty' between song repartee rather than the music it seems to exist to detract from...

Having said that, I got out of the wrong side of bed this morning.

Cheers
